  1. Renaming H.Sapiens Julian Cribb, FTSE ANU Emeritus Faculty October 24, 2012

  2. Linnaeus • Carle von Linné (Linnaeus) 1707-78 ‘Father of Taxonomy’ • SystemaNaturae1735 proposes bionomial classification system • Names H. sapiens, 1758, in ‘anthropomorpha’

  3. A new name?

  4. Extinctions • Past extinctions: • Ordovician – 440 my BP – 25% of families lost • Devonian, 370 my – 19% lost • Permian – 245my – 54% of families lost (96% 0f marine species) • Triassic – 210my – 23% lost • KT – 65my – 17% lost • Anthropocene extinction: • >30,000 species/year lost (Wilson) • Hunting (megafauna); farming ; Earth system modification. • First biotically-caused extinction (Eldredge).

  5. Global climate +4-5o Global carbon emissions now tracking A1F1 (high) scenario • 2 degrees of warming by 2050 locked in • 4-5 degrees of warming by 2100 probable • ‘runaway’ warming of 10-400 degrees possible Source: IPCC

  6. Chemical assault • 83,000 man-made chemicals (USEPA) • 550 have known risks • New, untested chemicals released constantly, eg 1000+ nanosubstances • Earthwide contamination via water, air, soil and life • Extensive contamination of mother’s milk, food • >287 industrial chemicals (inc. 180 carcinogens) found in US newborns

  7. Dead zones • 476 ‘dead zones’ worldwide, driven by NPK discharge into oceans and estuaries

  8. Our vanishing land “The Earth is losing topsoil at a rate of 75 to 100 GT. per year. If soil loss continues at present rates, it is estimated that there is only another 48 years of topsoil left.” - Marler & Wallin, Nutrition Security Institute, USA, 2006

  9. Food waste Source: USDA, NYT

  10. Peak water “Current estimates indicate we will not have enough water to feed ourselves in 25 years time...” – Colin Chartres, IWMI Groundwater mining Disappearing rivers Vanishing lakes Shrinking glaciers

  11. Peak resources Peak oil 2006 Peak Fish 2004 Peak P 2030-40? Forest loss: 6.4mha/yr

  12. Our global footprint Source: GFN 2012

  13. Weapons • Annual global weapons spend: $1,600 billion (SIPRI) • Annual global spend on food R&D: $50bn (Pardey&al.) • 20,000 nuclear warheads still exist • 19 nations have nuclear capacity Not-so-

  14. Money The main instrument of destruction is something which does not exist in the natural World, and now mostly consists of electrons. Money is a figment of the human imagination. If we run short of money we simply create more (=GFC).

  15. Was Hans Andersen right? We are trading things that are real and finite – eg soil, water, natural resources, species and atmosphere – for something which is unreal and infinite: money.

  16. Boundaries we dare not cross... Source: Rockstrom et al. 2009

  17. ‘Wise, wise man’

  18. Achievements

  19. Population and food Global food demand to double

  20. Taxonomy

  21. What should we call ourselves? She’ll be right, mate! • Pan daemonicus – the ‘demon chimp’ • Homo profligans • Homo stultus • Homo struthiones (ostrich man) • Yahoo vulgaris (vulgar yahoo, after Swift) • Homo erectus dyfunctionalis • Homo drongo • Homo gluteus sapiens • http://goo.gl/J8Jv0
